Polymarket US gives new users a $50 promotional trading credit after a deposit of at least $10 made through a campaign code or link, one per person. The credit cannot be withdrawn as cash — only what it earns once contracts settle. From 2 October 2026 the credits expire a set number of days after they are issued.

Spent on a contract priced at 50¢, the $50 credit buys 100 contracts. They pay $100 if they settle YES and nothing if NO, so at a fair price the credit is worth $50 on average — less the taker fee, which peaks at $1.74 per 100 contracts at 50¢. Call it about $48.
The $10 deposit is not a cost: it stays your money. The cost is the time limit (from 2 October) and the fact that the credit is only worth anything if you trade it.
Only settled proceeds can be withdrawn, and only after you have linked a payment method and deposited — so the credit cannot be taken out without trading.
A promo code is typed in at sign-up; a referral link carries the same code for you, and it usually pays the person who shared it too. On a regulated exchange both are incentive programmes the operator files with the CFTC, so the terms are the operator’s — whoever’s code you use. That is why this page quotes the operator rather than a partner.
Affiliate sites advertise Polymarket US codes of their own; the amounts we saw match the operator’s $50-for-$10 programme. Polymarket US says it issues codes per campaign, so any valid campaign code leads to the same offer.

18+ only. Event contracts can lose their whole value, and a promotional credit does not change that. Offers change without notice: check the operator’s current terms before you deposit. The CFTC has warned exchanges about how incentive programmes are marketed — our report on its August 2026 advisory. If trading stops being fun, see responsible trading.
